Title: $50 ebay pcp pumps?
Post by: DU-BB on November 05, 2017, 08:15:03 AM

These are very tempting, but they are metric, not NPT. Has anyone ever tried one of these?

I couldn't find an adapter for it anywhere.

these are crap, I would not buy them again! I have one here, when sent to me, I put the pump together and the threads were all stripped out, and doesn't work. Waist of time and money. will just save up and get a shoebox or other 4500 psi pump

I talked to a friend of mine who works at the scrap yard, he told me that have a couple of high pressure scuba/scba compressors out there, and that I can buy one from there for $0.39 per pound! The question now, is, what do they weigh? I have to love that, they sell everything by the pound, unbelievable! He brought me a couple of cool argon lab lasers, once, too. They get all kinds of strange things that come in. By the pound, can you believe it?

I'm thinking that the threads all stripped out because, as I said, they are metric. They won't interchange with NPT sizes without some kind of adapter. I couldn't find an adapter.
